Three Dollar Quill

Okay, so I gave myself sort of a break today, focusing on improving various bits of MOTR. I finally settled on calling it a Matrix, and this cascaded into a bunch of renames that made things clearer. And made a few other changes.

That added up to enough clarity and motivation that I finally added a line of test coverage. Now, I'm not sure how best to handle the remaining lines in the matrix module, because the vast majority of those lines are validation failures or similar. I guess there's nothing for it but to carefully construct a bunch of axes "wrong" to make sure they hit the validation errors...

To get that done, I guess I just need to be in the right frame of mind to power through the monotony. Anyway, it's past time I meant to post this; I need to get to bed now.

Good night.
